I remember when "interactive TV" was a favorite buzzword. A few people kept asking if this was really a viable concept, if viewers would really and truly interact with a program instead of passively viewing it. They were often shouted down in the craze to sell a new service.
What has changed? We do see some interactive uses for picking what to view, and even commenting on it after we've viewed it. But I still don't see people interacting *while* viewing a program itself.
And as far as "live streaming" is concerned, it fills in a gap for those types of content suited for one-time viewing, like sports. But it doesn't change the game for all of the other types of content (including concerts) that people can enjoy on their own schedule, or that wish to view the content more than once. The on-demand types of streaming are still the most important development in content delivery for the foreseeable future.
